TOOLS REQUIRED
J 38125-C Terminal Repair Kit
The Supplemental Inflatable Restraint (SIR) System/Supplemental Restraint System (SRS) requires special wiring repair procedures due to the sensitive
nature of the circuitry. Follow the specific procedures and instructions when working with the SIR/SRS system wiring, and the wiring components (such
as connectors and terminals).
IMPORTANT: Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals unless specifically indicated by the terminal
package.
The tool kit J 38125-C contains the following items:
-

The sealed splices have the following 2 critical features:
-
A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside.
-
A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits.
The J 38125-C also serves as a generic terminal repair kit. The kit contains the following items:
-
A large sampling of common electrical terminals
-
The correct tools in order to attach the terminals to the wires
-
The correct tools in order to remove the terminals from the connectors
